Hot Melt Glue for Mattress Foam  

The right mattress glue boosts efficiency

Mattress adhesive brings along great advantages, not only due to its properties, but also the variety of possible application methods and equipment that can be customized to become an integral part of the production process. Once the adhesive application is integrated into the process, the overall efficiency improves regarding both cost and time in production, packaging, storing and transport.

The mattress adhesive application  methods include rolling, spraying and beads. All these methods can be realized manually, semi automatically or automatically. For all these application methods to be optimal, proper implementation and training are required. Manufacturers of mattress adhesives provide products, suitable equipment and training to guarantee you the most efficiency.

New technologies allow for more and more efficient systems:

• Plug-and-play easy spray systems:  an application process can be given a boost by using an easy to use spray system. These are often fully mobile and can be used in any location as long as compressed air connection is available. All you need to do is plug in the system and start spraying the mattress glue. Beds are ready remarkably faster when this method is used.
• Zero overspray systems:  the development in transfer efficiency has resulted in zero overspray systems which represent 100% transfer efficiency. This means that all the adhesives for mattresses applied will be used, and none will be lost. These systems are enabled by the right combination of mattress adhesive and the right advanced application method.
• Immediately curing products:  water based mattress adhesive systems that cure immediately, through forced curing process, remarkably improve process efficiency. The zero curing time allows for an uninterrupted flow of adhesive application, product processing and packaging. This allows for improved cost and time efficiency as well as controlled processes throughout the production without compromising to quality. This not only improves the mattress assembly process but thanks to this glue beds are generally produced faster.

1. Solvent based mattress glue solutions

The most traditional form of mattress adhesives are solvent based systems. These systems provide strong bonds, generally stronger than water based mattress glues. They can be applied by roll coating, spray or beads and dots.

The disadvantage of solvent born mattress adhesives is that they tend to release solvent fumes and adhesive residue in the air as they set when the solvent evaporates. Nevertheless, the new technologies allow for more user friendly systems where the share of solid parts is higher. This results in less solvent in the product as well as reduces the amount of product needed to complete the application.

2. Waterborne mattress adhesives

The great advantage of  waterborne mattress adhesive  is that it is environmentally friendly, releasing only water while setting by evaporation. The evaporation process, however, generally takes longer than when working with solvent containing products. If the longer setting time is not taken into consideration, the water may remain in the mattress and encourage mold forming once packed in plastic. Fortunately, the development of adhesive technology makes it possible to let the water based mattress adhesives cure faster and minimize overspray.

3. Hot melt mattress adhesive

The newest, and most efficient mattress adhesive on the market is hot melt which is applied with hot air and sets as the heat dissipates. Hot melt is the mattress glue with the fastest curing process and least risks as it involves neither solvents nor water thanks to its 100% solid consistency.

Hot melt glues have rapid initial tack which allows for more efficient processes and requires less mattress adhesives. The only downside of mattresses that use hot melt, is that they may make a cracking noise when the adhesive is dry. However, the  continuous development and innovation  are removing this disadvantage.

Hot melt adhesives for mattresses are usually applied as spray regardless whether they are a one or two component systems. There are also rollable formulations of hot melt mattress adhesives made possible by reducing the solid share to about 75%.
